CATL and BYD Battery Exports: How China Controls 76% of Global EV Cell Production
CATL and BYD together dominate global EV battery cell manufacturing, with expanding factory footprints in Hungary, Morocco, and Brazil reshaping trade flows and triggering subsidy scrutiny from the EU and US.

The scale of Chinese battery cell dominance#
China produced over 76% of all lithium-ion battery cells globally in 2025, with CATL alone accounting for roughly 37% of global EV battery installations. BYD captured an additional 16% share through its vertically integrated Blade Battery platform. This concentration has created a structural dependency across the automotive industry that even aggressive reshoring policies have struggled to dislodge. The sheer volume advantage translates into cost differentials of 20-30% compared to Korean and Japanese rivals, making Chinese cells the default choice for price-sensitive OEMs.
Overseas factory buildout and trade route shifts#
CATL broke ground on its Hungarian gigafactory in Debrecen with a planned capacity of 100 GWh, enough to supply roughly 1.5 million EVs annually. BYD simultaneously expanded its Morocco facility to serve both European and African markets while avoiding EU anti-subsidy tariffs on Chinese-origin goods. These localisation strategies are deliberately designed to qualify for regional content requirements under EU and USMCA trade rules. The result is a complex web of component trade flows where cathode materials still originate in China but final cell assembly occurs closer to end markets.
Raw material control as a competitive moat#
Both CATL and BYD have secured upstream positions in lithium, cobalt, and nickel supply chains across Australia, Indonesia, and the DRC. CATL owns stakes in lithium mines in Argentina and has long-term offtake agreements covering an estimated 60% of its raw material needs through 2030. This vertical integration allows Chinese battery makers to weather commodity price spikes that squeeze competitors reliant on spot markets. The strategic implication is that even when cell manufacturing moves offshore, the critical mineral supply chain remains anchored in Chinese-controlled assets.

Technology leadership in sodium-ion and solid-state#
CATL commenced mass production of first-generation sodium-ion batteries in 2025, targeting the energy storage and low-cost EV segments where lithium price sensitivity is highest. BYD has invested heavily in semi-solid-state battery research, with pilot production lines expected to reach commercial scale by late 2027. These next-generation chemistries could further widen the gap with competitors who remain focused on incremental improvements to existing lithium-iron-phosphate and nickel-manganese-cobalt platforms. For importers, the technology roadmap suggests Chinese dominance will persist even as battery chemistry evolves.
Trade policy responses and tariff exposure#
The EU imposed countervailing duties of up to 38.1% on Chinese-origin EV batteries in late 2025, while the US maintained Section 301 tariffs and introduced IRA-linked sourcing requirements that effectively exclude Chinese cells from federal subsidies. These measures have accelerated the localisation trend but have not reduced overall Chinese market share, as CATL and BYD simply shift final assembly to tariff-friendly jurisdictions. Businesses importing batteries or battery-dependent products need to map their entire supply chain to assess cumulative tariff exposure and rules-of-origin compliance.
People also ask
What percentage of global EV batteries does China produce?
China produced approximately 76% of global lithium-ion battery cells in 2025, with CATL and BYD together accounting for over half of all EV battery installations worldwide.
Are CATL batteries subject to EU tariffs?
Yes, EU countervailing duties of up to 38.1% apply to Chinese-origin battery cells, which is driving CATL to localise production in Hungary to qualify as EU-manufactured goods.
How does BYD Blade Battery differ from CATL cells?
BYD Blade Battery uses a cell-to-pack lithium-iron-phosphate design that eliminates traditional modules, offering improved safety and energy density while being manufactured in-house for BYD vehicles.
